On a 4:3 aspect ratio you get a larger vertical size so you can display more up and down the way than on a wide-screen monitor. But without the large size and resolution the whole screen would mean nothing. Thats like trying to play a blu ray dvd on a 32inch chunky screen crt tv its just as blurry as the normal dvd would be you need to view it on a screen that is high resolution too. You just cant see it all on different ratios its hidden its cut off its bigger than what can be displayed it needs to be in its native resolution and aspect ratio, that is why you get bars on things made for 4:3 if displayed on a widescreen display that is why you get bars on the opposite too. What he is saying is that on a PDF that is taller than wider you would need to scroll to be able to see everything on 16:10 but on 4:3 you see more because it is physically taller but it may be all stretched looking or pixelated if the res is not high. Resolution if effected by screen size because in actuality a larger res is a larger picture the pc is just zooming out or resizing to fit it on your smaller screen or stretching to fit it on a screen thats too big! A large 1980x1080 picture would be cut off on my pc screen so it changes the zoom it makes it smaller not in res but viewing size. I can see it fully it just zooms it, the detail is still there if i zoom in but it only displays part of the picture if i zoom in the rest is cut off because my display is to small to show it. Example you walk up to a painting and look at it but your too close to see it all so you walk back to see it all, you cant make out all the definition or detail when walking out because its far away. Its like to see a mountain range you have to be far away but to see the rocks on it you have to be very close up or on the mountain itself. Pictures and screens are like this, large resolutions have detail but you need a big screen to be able to stretch it out to see it all in detail or you have to zoom in and just view part of it, it just makes it smaller to fit on a smaller screen the detail is still there you just cant see it without zooming in. So if a widescreen monitor has a larger res than a 4:3 screen it will have a lots more detail but it will either be zoomed in and small looking or zoomed out and have part of it cut off, unless its smaller than the displays res then it is in actually smaller than the screen itself and it will be in only part of the screen then you can stretch it to make it larger but it gets pixelated. The 4:3 might be able to display it all but it will be pixelated because of the resolution. My 32inch crt tv might be able to show me a bigger display and show me more of a document but i wont use it because it wont be as detailed as my monitor will i wouldnt be able to view it correctly on the tv. I would need to zoom in on a 16:10 monitor to read the PDF on a 4:3 monitor it can display more up the way so there is less need to zoom. There is a larger viewing angle up the way, not an approximation just a sketch to show what he is saying. But he fails to see that the widescreen with larger resolution would be better because it has more detail in it and it would be able to show more off due to this its just got a bit cut off at the bottom because the PDF or whatever is a different res to the screen its much larger or much smaller than the screen. You have to shrink or stretch things depending on its resolution and your monitors viewing size. To combat that you get a larger screen with a larger size res, keeping the same res would just stretch the picture. LIKE that monitor that was on the news section the actual performance was shit because it was just 3 1440 x something monitors side by side.
